Riveted Inboard Left Wing bottom skin. No need to bend aluminum back as described in the manual. I clecoed the entire inboard skin and was able to reach every rivet through the access panel openings. It wasn't easy but was able to complete the inboard skin without any help. I purposefully left the two most inboard ribs out so as to reach the third rib from the inboard end of the wing since the flange faces inboard and cannot be reached from the inboard most access panel. see photos....
